Chapter 7, Problem 7.41P
The 2000-lb weight of the trailer is distributed equally between its two wheels, one on each side of the trailer. The center of gravity is at G, and the wheels are free to rotate. Determine whether the trailer can be pushed over a 6-in. curb without tipping, and, if so, compute the required horizontal force P.
